To bisect and angle, put your compass on the vertex of the angle (I'm going to use
I went ahead and labeled where it intersected
Now put your compass on
Now do this same thing with another angle. I'm going to use
Do you see where those two lines intersect? That's the
NOTE: My diagrams are inaccurate. However, the method will always work. I was just using computer software and was unable to use an actual compass - so my attempt is not perfect!
